So I swapped to a smooth front fender and running bullet tails. The bullets use purple wire for signals, blue for running/brake, and black for ground of course.
I clipped the original twilight harness from the old tailight off and went to wire the lights.
I have my signals and brake lights working but I can't get running lights. I have a blue wire (goes to a light fuse) and an orange and white wire (says accessory) left over.
I can wire it so I have running lights but no brakes or signals. I need all three.
I also bought a custom dynamics module thinking that would help but so far it hasn't just gives me strobe options etc.

 

2001 Fatboy by the way. Thanks!
